Improved air compressor waste heat recovery device

The utility model relates to the technical field of air compressor waste heat recovery, in particular to an improved air compressor waste heat recovery device. An improved air compressor waste heat recovery device comprises a compressor, a conversion water tank and a water storage tank, the compressor is connected with the conversion water tank through an oil pipe, the water storage tank is externally connected with a water pipe, the water storage tank is connected with the conversion water tank through a water pipe, and the conversion water tank is provided with a heat transfer pipe and a temperature sensor. By optimizing the structure of the conversion water tank, redundant heat can be recycled again, the heat is prevented from being directly transmitted into air, the heat can be converted in time, the construction environment temperature is stable, the air compressor is prevented from being in a high-heat construction state all the time, and production safety is guaranteed; and meanwhile, heat converted fr
